Search and rob a potential killer (5)
I believe the answer is:
rifle
This might be a double definition.
'search' is the first definition.
(as in rifling around for something)
'rob a potential killer' is the second definition.
'rifle' can be an answer for 'rob' (I've seen this in another clue). I am not certain of the 'a potential killer' bit.
'and' is the link.
Can you help me to learn more?
(Other definitions for rifle that I've seen before include "loot in sack" , "Gun; sack" , "Security provider with stock" , "Firearm - plunder" , "Steal and carry off - firearm" .)
